To all whom t may concern.'

Bc it known that I, JOHN T. CoLLINs, a citizen of the United States, residin at Kokomo, in the county of Howard and tate of Indiana, have invented certain new and useful Improvements in a Heater, of which the following is a specification.

This invention relates to new and useful improvements in heaters, the primary object of the invention being to provide an attachment for a furnace whereby the maximum amount of heat may be derived therefrom. Y

Another important object of the invention is to provide a device of the above nature including means whereby the fire around the walls of the furnace is compelled to burn more violently than the fire in the center of the furnace thereby heating the walls of the furnace to heat air surrounding the same.

-My invention also consists in the construction, arrangement and combination of parts to be more fully set forth in the following description and accompanying drawings, and pointed out in the appended claims.

In the accompanying drawings forming a Y part of the description and wherein like numerals are employed to designate like parts throughout the several views,

Figure 1 is a vertical section taken through the heater, the casing therefor being shown in dotted lines,

Figure 2 is a horizontal section taken on the line 2 2 'of Figure 1,

Figure 3 is a vertical section through the radiator taken on the line 3-3 of Fig. 2,

Figure 4 is a vertical section of the radiator taken on the line 1 -4 of Fig. 2,

Figure 5 is a transverse section of the Aradiator taken adjacent the bottom thereof,

Figure 6 is a bottom plan of my center fuel Figure 7 is a transverse section of the same taken on the line 7 7 of Fig. 6, and

Figure 8 is a transverse section of my improved center fuel plate as applied to a revolvin grate. In t e drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 9 designates a furnace of any desired construction havingV locatedtherein the usual fire ot '10 under-which is positioned any type o grate 11, preferably 'of the rocking type as shown in Fig. 1 orof the revolving type as i1lus trated in Fig. 8.

What'I term as mycenter fuel plate is. g"

designated by the numeral 12 and assumes the form of a circular plate 12 which may be either positioned centrally of the' grate and slightly thereabove as most clearly shown in Fig. 1 of the drawings or may rest on the grate. This plate is provided Vwith an annular, depending flange equipped with radial passages therethrough to recelve a ortion of legs 1311s shown in Fig. 6, each o which is slotted to receive therein the shank of a bolt 14 whereby the legs are adjustably associated with the under side of the fuel plate. Preferably, these supporting legs radiate from the fuel plate, and the circumferential edge of the plate is under cut whereas the plate lipay receive the maximum amount ofV coal or When a fire has been madeV in the furnace, it will be seen that the tire will burn intensely'around the ed e of the center fuel plate, and the fire wil eventually burn its way up over the plate. Consequently the fire may be managed so-'that the burning mass is concentrated around the edge of the plate and whereby the walls 'of the lire pot and furnace may be heated to a maximum point whereby the furnace will give out the, greatest amount of heat. Howeverg should the fire burn up over the center fuel late, the live or hot coals may be removed t with a pokerr'or any other suitable implement so that the hot fire will be maintained around the edge of the plate and adjacent the walls of the furnace. 'Them fresh ycoal or fuel is shoveled directlyupon the center fuel plate to be consumed in the manner above setfforth.

This center lfuel plate when `associated with formin a. part of a revolving grate 15 as shown in Fig. 8 of the drawings, arssumes the form of a circular plate" 12', which is equipped with a centrally disposed depending projection 16. This Vprojection 16 is mounted in an axially disposed socket carried' by the supporting spider 17, the arms of which are secured to the furnace or fire pot in anysuitable manner. This socket supporting bracket is equipped with a plurality of Vball bearings 18 to engage the under face of the plate 12 to permit of the revolving grate to be movedV more readily when it is shaken or revolvetl. Y i

The improved radiator which'isjarranged in close proximity to the furnace 9, consists of a vertically vdisposed cylindrical easing erefrom tically therethrough, the lower end of the pipe beingY flush with the bottom of the radiator .casing and having its edges secured to the`l` edges of an opening provided in the bottom of the casing 11). The upper end ot the hot air 'pipe 22 extends through an openingr in the top of theeasing, a substantial distance thereheyond or may be secured to the top of the casing in the same manner as the lower end of the pipe; The hot air from the pipe 22 mingles with the air in the casing` 25 and rises into the hot air outlet pipe Q4 to beconveyed to various rooms. As most clearly shown in Fig. 2 oi. the drawings, the casing 25, is provided upon opposite sides with extensions 26 arranged adjacent the lower edge oi' the casing and provided with air inlet openings 27, whereby cool air may be admitted to the lower end of the casing. A plurality oi'radiating partitions are provide-d within the radiator. and one longitudinal edge of each is secured to the inner surface'of the radiator side walls, while the other longitudinal edge of each partition is secured in any suitable manner to the relative outer surface of the hot air pipe 22. These partitions are provided solely for the purpose of retarding the products of combustion delivered from the furnace around the/.hot air pipe 22, so that. cool air passing up therethrough will become heated to a high degree. One of these partitions Q8, which l term a dividing partition, extends from the top-to the bottom of the radiator casing and is of course,

" disposed verticaily between the two conduit pipes 21 which lead from the furnace, whereby air from one conduit is caused to pass around one side oi the radiator, while the air from the other conduit is caused to pass around the opposite side of the radiator. A pair of diametrically disposed partitions Q9 are also arranged within the radiator and at right angles tothe dividing partition. These partitions QS) extend from the top of the radiator, to a point spaced from the hottoY from the conductingr pipes Q1.

tom thereof, whereby products of combus tion are caused to travel to the lower end of the radiator'after being delivered therein- A second air of partitions 3() are also provided with-` in the radiator and radiate from the center ln order to provide a draft, and in orderV s that the products of combustion will be caused to travel in the preferred course, a pipe 3l is led 'from the lower end. ofthe radiator, through the side of the casing 25 and terminates a short distance from the outer side of the casing 25. This end of the pipe is closed by a door 32 pivotallyconnected to the end of the pipe 31 whereby the door may be opened and a suitable clean ing implement inserted to gain access to the interior of the radiator for cleaning purposes. A pipe rises from the pipe 31 to conduct smoke to a chimney from the radiu ator. It is, of course, to he understood that l may empioy as many hot through the radiator, as may be necessary to moet varying conditions, and that the pipes may be of anyrdesired shape, and that other partitions, and other arrangements of air pipes 22 partitions may be provided to accomplish the functions above set fort As set forth previously, the center Enel plate 12, will cause the fire in the Jfurnace to burn most intensely around the walls of the furnace, and consequently of heat will he caused to radiate from the walls of the furnace. This heated air will oi course travel upwardly within` the casing 25, to the heat conducting pipe 24C. Further, a great amount of hot air wiil pass through the conducting pipes 21 as will all smoke, and what flames may leap from the tire. TheV products of combustion which are delivered into the radiator, will he caused hy the dividingr partition 28 to travel around top of the partitions 30. By this time it is estimated that quite a bit of heat will be derived from the products of combustiondelivered from the urnace and due to the draft caused by the pipe 33, the smoke will be caused to travel downwardly of the radiator to escape into the outlet pipe 31 and greater amount u;

then into the pipe 33. The cool air admitted to the bottom of the casing 25, through the inlet openings 27 will rise up through the hot air pipe 22 Where it will be heated by the hot air in the radiator, and after being heated to the maximum point, passes up through the pipe 23 and thence into the conducting pipe 24 which delivers hot air to the various rooms of a building.

The foregoing description and accompanying drawings have reference to what might be considered to be the approved or preferred form of my invention. I desire it to be understood that I may make such changes in the construction, combination and arrangement of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the invention as claimed hereinafter.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent, is

l. The combination with a furnace including a fire pot and a grate disposed below the fire pot, of a fuel plate for the furnace including a circular imperforate body disposed axially within the fire pot at the lower end thereof and spaced equi-distantly from the inner surface of the fire pot, and means carried by the plate for engaging the fire pot.

2. The combination with a furnace and grate therefor, a fire pot disposed above the grate, of a fuel plate for the furnace embodying a disk-shaped imperforate body disposed axially in the fire pot adjacent to the lower edge thereof and having its outer edge spaced equi-distantly from the inner surface of the fire pot, the body being disposed above the grate in spaced relation thereto, and adjustable radially extending legs carried by the lower surface of the plate for engaging the fire pot.

3. In a furnace, a fuel plate including a flat imperforate body, a depending flange formed on the lower end of the body and having guide-ways formed therein, out- Wardly extending slotted arms carried by the lower surface of the body extending through the guide-Ways, and bolts carried by the body extending through the slots for holding the arms in an adjusted position on the body, the outer ends of the arms being adapted `to engage the fire pot of the furnace.

In testimony whereof I allix my signature in presence of two witnesses:
